To me, this goes back to the difference between "everything" we perceive and perception itself, which is what Mike is driving at.
Hmm. Not really. Even the act of perception itself occurs within a contextualized conscious and subconscious framework, but I'll grant you awareness is not that.
What Healje is apparently driving at is a physical process that he can re-engineer back to physical fundamentals in the brain, and which he can play forward in an increasingly complex step order arriving at "everything you consciously perceive."
I'm not driving at that in particular, but only trying to point out the central role the subconscious mind plays in our having awareness and perception - something largely ignored here.
In this way, perception itself is held as an emergent quality of this physical step process to which awareness is unaware.
It's definitely an emergent quality, but I'm certainly not talking about a 'physical step process'. You'd have to really broaden your ideas about the brain to even come close. Whatever physical processes are involved they are far from step-wise. They are instead incredibly distributed, concurrent, and hierarchal at relatively incomprehensible levels of each.
It's telling to note that hard science can take us far up this ladder of complexity, but stops dead at the threshold of awareness, which is sometimes described as the emergent result of data processing, of all that locomotion going on "under the hood."
Oh, it doesn't stop dead at all; our understanding is growing every day. That we can't pinpoint or describe the process of emergence doesn't in any way mean it isn't or that mind is the result of panpsychic phenomenon as you continually claim. And emergent from locomotion under the hood? Yes. Emergent from data processing? No.
It's worth noting that this belief is not drawn from examining the phenomenon itself, but rather the physical processes believed to "create" it. This strategy has worked wonderfully so long at the phenomenon in question is observable - that is, with every other phenomenon in reality other than perception.
Actually, my thoughts and beliefs around 'mind' are drawn in part from examining the phenomenon itself, from science, and from common sense. The latter comes into play in numerous ways such as observing the 1:1 correlation between brains and consciousness; in understanding the mind isn't querying the eye for photon strikes and then consciously constructing 'red'; and in noting the effect of insults to the brain on mind and self, such as in people who have lost their short-term memory.

For starters, I have never advocated a Panpsychic take on anything.
You seem convinced that you can scientifically demonstrate how the subconscious mind creates ("in our having") awareness. How so?
What's more, you insist that quantification (science) derived from directly measuring observed phenomenon does NOT stop dead at the threshold of awareness, which you posit as an emergent phenomenon (again, emergence is not scientific) arising out of a highly complex and distributed physical system, including the subconscious mind. In what manner do you propose to cross the threshold by way of quantifications?
It is this sticking point that leading neuroscientists have repeatedly said, in so may words, "we have no idea what a scientific model would even look like."
Whatever model you have in mind, it ain't going to be scientific as we normally use the word. I'm not convinced you understand exactly what that means.
This to me is not a matter of crossing some theoretical "gap" in our understanding, because that assumes that a step process up a theoretical ladder of complexity and distribution "explains" consciousness - once we close the "gap."
When you finally realize what physicalists consider an "explanation," you smile to yourself.

When you claim the mind isn't emergent from the brain you are explicitly making an unavoidable claim falling under one panpsychism / metaphysical variant or another. You can't have it both ways. I mean come on, 20k posts later it could be time to step up and just own that sh#t.
You seem convinced that you can scientifically demonstrate how the subconscious mind creates ("in our having") awareness. How so?
No, I don't. And I also don't think the subconscious mind creates awareness - I think the subconscious and conscious minds are distinct and both are emergent.

I've several times now said that the complexity of brain could easily put the problem beyond our grasp. Our knowledge is insufficient at every level of study - hell, we have little more than a rudimentary picture of the brain's neural anatomy and connectome and know next to nothing about how genetic expression regulates individual and collective cell behavior. We're currently just trying to statically model a physical cubic millimeter of brain tissue sans all behavior and that's only just within our grasp let alone whole brains. To be honest, the brain is such an energy efficient organ that we will likely never be able to functionally model it simply due to the fact we can't come close to matching its raw capabilities and without being able to model it at a high level I don't think we well every understand how emergence works. It's more likely the best we'll be able to do is to identify more closely when emergence and coherent awareness occur through a better understanding of brainwaves rather than a bottom-up model. So while we have no current answer for emergence, there is nothing dead stop about research at that boundary.
It is this sticking point that leading neuroscientists have repeatedly said, in so many words, "we have no idea what a scientific model would even look like."
Exactly, we don't even have a physical model let alone a functional theoretical one.
Whatever model you have in mind, it ain't going to be scientific as we normally use the word. I'm not convinced you understand exactly what that means.
I don't have a model in mind, what I have is:
a) the observation of a 1:1 correlation between brains and minds
b) the fact the conscious mind does not create or form 'red' but rather has it handed to it - i.e. there is a subconscious agent upon which the conscious mind is dependent
c) I can see the 'emergence' of the brain/mind evolutionarily, in extant species, and in newborns.
This to me is not a matter of crossing some theoretical "gap" in our understanding, because that assumes that a step process up a theoretical ladder of complexity and distribution "explains" consciousness - once we close the "gap."
Again, the notion of a 'step process' when it comes to the brain is blithely naive and I don't purport to explain consciousness, only to say I find metaphysical explanations both unnecessary and highly unlikely.

Here's another mathematical approach to brain/mind. Karl Friston is the most cited neuroscientist in the world, and his attempts at explanations of how the mind and body work arise from a concept he calls free energy. In a nutshell, the mind predicts a physical motion, like raising one's arm, and the body reacts in a way that minimizes free energy (or prediction error). The mathematics is somewhat incomprehensible, although I have played with functional integrals a bit.
I don't know how much predictive value this notion has, and it might be vaguely comparable in this aspect to Tononi's Phi function. It looks pretty vague to me.

Healyje,
Again, you have theories. Is there anything else that you have? Would experience be something else, or would that again be simply the presentation of another theory for you? If one can only talk about something theoretically, then what are the theories based upon? At the bottom of everything, underneath all of those theories, is there something that you can fully rely upon, something that you can know that you know unequivocally, the most basic element that IS available?

Except, perhaps, when a sabre-tooth tiger or cave bear is about to tear you to pieces. I doubt that the mind has a single optimization strategy.

It's funny how some folks can't stand the idea the beauty, art, and wonder of the mind emerges from something as base and primitive as mere meat. Yet, when pushed to say what metaphysical variant they hold to instead, none but Werner speaks up.

--
A is Identity theory, where brain states and conscious states are held to be identical. Look that up for yourself and find the impossibilities. It is logically incoherent - you can easily see why.
If you were to say that the brain and mind are functionally related, you would be correct in my view. There is nothing that is NOT functionally related to everything else.
B The brain creates content. I've said that all along. You won't win many logic contests arguing the virtues of complexity and emergence while at the same time arguing that higher levels of complexity are not sourced (or if you like, created) by lower levels. Your use of the word "dependent" implies both a step process AND a forward causal chain, otherwise you could confidently say that the unconscious mind is dependent on awareness, and that less complex functions "emerge" from phenomenon with greater complexity - and you clearly are not saying that.
c You can see the emergence of increasingly complex brain function (content production) in evolutionary terms, but not the fact that we are aware of same. If you could, you could demonstrate how a specie went from no awareness to being aware, strictly in terms of quantifications derived from observable phenomenon. We can observe what we think is the presence of awareness in others, but we can find no empirical proof of same through investigating the brain itself. That's the rub.
Now if you were to say you have studied the brain scientifically, and like IIT, decided to launch into speculation about being conscious, that would be one thing, and I applaud you for the effort. But your speculations will not themselves be scientific because they will not be measurements directly drawn from observable external phenomenon.
Yes, we can say that baby over there appears to be conscious, and her brain output we can observe developing over time. But awareness itself never changes because it is not a thing that can ever be anything but what it is.

IMO, this thread can rock sometimes when the riff falls within the scientific worldview. There is a likely reason for that. Science is always advancing, and it advances on many fronts simultaneously. It's hard to keep up with it all even when you're tuned-in to wanting to know. And it's advancing at an accelerated rate.
The question of whether mind evolved or whether it is this eternal thing that humans "discover" or something is completely uninteresting to me. It is like arguing whether evolution is true. The interesting issues to me in the scientific arena include the following:
How much of our mind is the result of unconscious processing? -- the point healyje makes a lot. From an evolutionary standpoint, it makes sense that the unconscious would be the equivalent of the underwater part of the iceberg with consciousness the visible part. I would add, also the evolutionarily-later part
Is Michael Gazzaniga's idea that what we have been calling mind on this thread is the result of a particular area in the left hemisphere of the brain that he designates the interpreter? The interpreter is not a decision-maker. Instead, its basically an after-the-fact story-teller that more or less represents you to yourself
Evolutionarily, what drove humans to evolve self-reflective consciousness? Seems like we could have been perfectly fine and maybe evolutionarily better off if we invested that in more intelligence rather than in self-reflective consciousness.
Do we actually have free will (in our usual sense of the term) or do we have just an illusion of free will?
What is it about humans that drives them to love, do art, feel awe, love to create, etc.?
What role do more or less intangible things like mathematics and software patterns play in tangible things like DNA-based evolution?
What is the interplay between intelligence and consciousness? Does one require the other?
Could we ever design true, human consciousness? How would we know that we did?
Could we ever preserve your or my consciousness as data?
What is the role of complexity in consciousness? Is there some threshold of complexity that is required before the magic begins?
What were the evolutionary pressures that led to the rapid development of the human brain during the Pleistocene?
Why is religion so prevalent?
How/why did morality evolve?
What is the interplay between natural selection and sexual selection in the evolution of humans in general and you or me in particular?
... gotta get back to work

A is Identity theory.
It has nothing whatsoever to do with Identity Theory and everything to do with the fact consciousness is only found in a 1:1 correlation with the immediate presence of a brain. The state mapping between the two is irrelevant to that basic observation.
B The brain creates content. I've said that all along. You won't win many logic contests arguing the virtues of complexity and emergence while at the same time arguing that higher levels of complexity are not sourced (or if you like, created) by lower levels. Your use of the word "dependent" implies both a step process AND a forward causal chain, otherwise you could confidently say that the unconscious mind is dependent on awareness, and that less complex functions "emerge" from phenomenon with greater complexity - and you clearly are not saying that.
The brain doesn't create content, the subconscious mind creates content.
Nothing about B) implies a step process at all, in fact, mind likely could never emerge from a step process. Subconscious by definition means not aware in the subjective experience meaning of the word. And I don't consider the subconscious a 'lower' order function or phenomenon, just a different one with a different role than the conscious mind. But yes, that the conscious mind is entirely dependent on the subconscious mind isn't rocket science when you consider 'red'.
C You can see the emergence of increasingly complex brain function (content production) in evolutionary terms, but not the fact that we are aware of same. If you could, you could demonstrate how a species went from no awareness to being aware, strictly in terms of quantifications derived from observable phenomenon. We can observe what we think is the presence of awareness in others, but we can find no empirical proof of same through investigating the brain itself. That's the rub.
Not 'content production'. What you can see is increasingly complex responses and behaviors which, at a point, by definition, require awareness. And you can, in fact, easily wire up some brains and determine the exact moment they become aware of prey.
Now if you were to say you have studied the brain scientifically, and like IIT, decided to launch into speculation about being conscious, that would be one thing, and I applaud you for the effort. But your speculations will not themselves be scientific because they will not be measurements directly drawn from observable external phenomenon.
IIT is 'speculative', not in any way 'scientific' from my perspective. My three observations are what they are and sufficient for me to take the positions I hold on the subject.
Yes, we can say that baby over there appears to be conscious, and her brain output we can observe developing over time. But awareness itself never changes because it is not a thing that can ever be anything but what it is.
The first undivided human cell of an embryo-to-be is not aware, nor is the first few million embryonic cells. Awareness evolves over the course of development so that newborn over there has a dynamic and evolving awareness which can be and is well-documented relative to its extent on a weekly basis over the first several years of life.
Again, if minds aren't emergent from brains then the only explanations left are either magical or metaphysical - take your pick, but it would be refreshing to hear how you believe it happens and why there would be any correlation at all between brains and consciousness.

- How much of our mind is the result of unconscious processing? | Yeah, the iceberg thing.
Is Michael Gazzaniga's idea that what we have been calling mind on this thread is the result of a particular area in the left hemisphere in the brain that he designates the interpreter? The interpreter is not a decision-maker. Instead, its basically an after-the-fact story-teller that more or less represents you to yourself. | There are a lot of supervisory-like theories along these lines - something provides coherence and continuity.
Evolutionarily, what drove humans to evolve self-reflective consciousness? | I'd say it's likely to have been a retro-evaluative function which came about in order to improve future odds after failing at hunting and/or mating.
Do we actually have free will (in our usual sense of the term) or do we have just an illusion of free will? | This one holds no interest or fascination for me...
What is it about humans that drives them to love, do art, feel awe, love to create, etc.? | I'd say pleasure and the capability, capacity, and the imagination necessary to run scenarios.
What role do more or less intangible things like mathematics and software patterns play in tangible things like DNA-based evolution? | I'd say it's an evolutionary selection loop like anything else.
What is the interplay between intelligence and consciousness? Does one require the other? | Clearly.
Could we ever design true, human consciousness? | No.
How would we know that we did? | It's not a relevant question given the previous no answer.
Could we ever possibly preserve your or my consciousness as data? | No, it's not data.
What is the role of complexity in consciousness? Is there some threshold of complexity that is required before the magic begins? | I'd say it plays both a gating and scaling role.
What were the evolutionary pressures that led to the rapid development of the human brain during the Pleistocene? | Pressures? Maybe just fortuitous opportunity that let to better a better in-and-out caloric ratio such that a high enough energy budget was available for extensive brain development.
Why is religion so prevalent? | Fear of the unknown and unanswered questions.
How/why did morality evolve? | Pain and empathy.
What is the interplay between natural selection and sexual selection in the evolution of humans in general and you or me in particular? | As Ed and I have posited earlier - predation and mating are probably the twin drivers of human evolution within a natural selection process relative to the current ecology.

What is the interplay between natural selection and sexual selection in the evolution of humans in general and you or me in particular?
The reason that I stated this one in this way is that I have been thinking for a while about "strategies" in human evolution. I'm just saying that I can imagine two successful lineages -- maybe yours or mine. The first might be primarily successful because of strategies most reliant on natural selection -- on surviving. The second might be successful mainly because of (your ancestors) impregnating more women than their rivals.

Probably a combination of both. Do you consider Mongols/Genghis Khan successful? He probably impregnated more women than any other man in history.

I consider Genghis Khan to be the most-successful male ever (possibly followed by Wilt Chamberlain) from a sexual-selection standpoint.
Of course, he also survived to come up to bat.

I agree. The contemplation of empty awareness is intriguing, but doesn't seem to lead anywhere, other than metaphysical speculations. Whereas science has a predictive quality, even if deep underlying components are not fully understood. And analogies between quantum experiments and meditative experiences may be fun to play with, but have led to no real conclusions. Correct me if I am in error.
The mathematics I've seen applied to consciousness and mind/body appear legitimate once one gets beyond the basic assumptions - but it's those quantified assumptions that seem dubious to me.
Please tell me if I am wrong. That's how one learns.
